A copy of Best Practices showed up on my doorstep on Tuesday. (along with a nice rut in my yard, where the UPS guy decided to turn around)

I'm guessing the two weeks is from the distributors having to ship to the chain bookstore's distribution systems, and then those stores needing to distribute it out to individual stores... the copy I have came straight from O'Reilly.

(And I'll have to thank TheDamian, as it was a curtesy copy from answering BBEdit questions)
